VIMPROVEMENT IN llRACTlON-ENGINES.

' Specification forming part of Letters Patent No. 174,706, dated March 14', 1876; application tiled January 11, 1876.

To all whom it may concern: p

yBe it known that I, CHRISTIAN R. SHIVE- LEY, of New Lebanon, in the county of Montgomery and State of Ohio, have invented eertain new and useful Improvements in Traction- Engines; and I do hereby declare that the lfollowing is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the ac compauying drawings, and to the letters of reference marked thereon, which form a part of this specification, in which- Figure 4l, Sheet 1, is a side elevation of a traction-engine embodying .my improvements. Fig. 2, Sheet 2, is an end elevation of the same on a smaller scale. Fig. 3, Sheet 2, is a sectional view, illustrating the manner in which the clutch is operated. Fig. 4, Sheet l 3, is a plan view of the frame-work on which the engine rests, and illustrates otherdetails not shown in the previous figures, as will be hereafter described.

This invention relates to that class of traction-engines employed for agricultural purposes, and which are so constructed as to transport themselves to the desired place, and there be converted into stationary engines for any ofthe usual purposes, such as driving thrashing-machines, Src.

The improvements consist in the combination of devices for imparting motion to the supporting-wheels, and for connecting and disconnecting them from the motive power at the will of the attendant; also, in the structure of the frame-work and the apparatus for guiding the machine; also, in the employment of a force-pump, attached to the machine in a peculiar manner, for use in case of iire or for other purposes.

I would thus proceed to describe my improvements and their adaptation to the engine:

A represents the boiler, B thecab, C the steam-chests, and D the ily-wheels, of the engine, provided with the necessary operative parts, as used upon the ordinary portable engines now in use, and supported upon the framework and driving and guiding wheels, the former represented by'E, the latter by F. The structure of the frame-work will be hereafter described. The customary fly-wheels D are keyed upon a shaft. This shaft is journaled upon the boiler, and further supported by the braces (curved) G, which are connected to the frame-Work and the cab, as represented. To the inner side of one or both of these flywheels, and revolving with them, is secured 'the beveled gear-wheel H. I represents a vertical worm-shaft, journaled in bearings at the side of the boiler A, and having keyed upon its top a beveled gear-wheel, a, dotted line, Fig. 1, which engages with the wheel H. Keyed upon the axle of the driving-wheels E is a gear-wheel, J, Figs. l and 3, rigidly attached to the side of which, and upon the same axle, is a clutch, b. The driving-wheel E has rigidly attached to it a corresponding clutch, c, operated by a forked lever, d', working in a slot in the periphery of the clutch, and passing upward into the cab wit-hin easy reach of attendant. Ihis lever is pivoted to an arm, e, Fig.,3, which is secured to the tire-chamber. The gear-wheel J engages with the worm I and receives motion from it.

When it is desired to have the machine pro pel itself, the engine is started, and the gearwheel J is put in motion, the shaft K revolving with it. The attendant grasps the lever d and throws the drivin g-wheel in till its clutch c engages with the clutch b upon the wheel J, when the wheel E will revolve and move the enginebackward or forward, as is desired.

It can be readily understood that both sides of the engineare provided with vertical wormshafts, actuated as just described, and imparting motionjto both the driving-wheels.

The frame-work of the machine, which is designed to be as springy and yielding as possible, while at the same time it is sufficiently strong that it may at once lessen and with-A stand the jar incident to the inequalities of the road, is constructed as follows, reference being had particularly to Fig. 4: Two beams, L, extend from the rear of the cab along each side of the lire-box, to which they are attached, and from that point converge, and are bolted or otherwise connected together in front at a point Ijust beyond the forward end of the boiler. To theunder sides of these beams are secured the journal-boxes, in which the shaft K revolves. An illustration of theboxes is to its under side the journal-boxes f, united by the flat cross-bar h. The semi-elliptical springs g, passing through the guideopenings of the boxes, and bolted to the under side of the fifth-wheel, rest upon the axle N, and aid' in sustaining any jar.

The driving-wheels are covered by a partial housing, consisting of semicircular plates 0, Fig. 1, attached firmly to the cab, as represented, and passing forward beyond it. At this end two spring-strips of seasoned wood are bolted to the plates O, and supported upon a cross-beam, P, resting on the beams L, pass forward, and are connected at their front ends by a cross metal spring, Q, having a concavity at its center, in which the forward end of the circular boiler rests. The forwardvend of the boiler is further supported upon a semi-elliptical spring, i, which is bolted upon the top ot' the fifth-wheel. The beams'L are also bolted to the top of the upper portion ofthe fifthwheel, and a king-bolt, j, pivoted in the crossbar h, has a head secured to the spring i. This bolt forms the pivot on which the fifth-wheel turns.

The mechanism for guiding the engine cousists ot' a rod, R, journaled upon the beam L and the fire-box, and having at its forward end a beveled gear-wheel, k, and at its rear end, which enters the cab, acrank, l. Suitably journaled upon the beams Lfjust'over the tth-wheel, is a Wormshaft, m, Fig. 4, on one end of which is keyed a beveled gear-wheel, n, Figs. 1 and 4, which engages with the wheel k upon the crank-rod R. An upright shaft, 0,

jonrnaled in a crossbeam, jp, has on its lower end a pinion, which engages with the teeth on the lower disk ot the lit'th-wheel s, and on its upper end a pinion, which engages with the worm q.

Now, by turning the crank l in the cab, the

fifth-wheel s, to which the forward axle M is upon the forsecured, is turned upon its pivot, carrying with it the forward wheels, which are thus made to guide themachine.

T represents an ordinary force-pump, secured upon the cross-beams L, justin front of the fire-chamber, and havingan' inductionnozzle, t, and an eductionnozzle,u, to which hose may be connected in any suitable manner. This pump is actuated by a piston attached to a crank-disk, fv, secured upon the lower end of a rod, U, journaled in a sliding bearing, w, which is attached tothe brace G by means of a clamp-screw, passing through a slot in tlie bearing, by which means the bearing carrying the shaft-rod U may be moved in or out to throw into or out of gear with the wheel H a beveled gear-wheel, W, keyed upon the top of the rod U.

Having thus fully described my invention,4

what I claim as new, and desire to secure by Letters Patent, is as follows:

l. In a tractionengine, the vertical wormshaft I, arranged as described, in combination with the ily-wheel D and axle K, with their connecting gearing, substantially as and for the purptse specified.

2. In a traction-engine, the force-pump T, located as described, in combination with the adjustable crank-rod U, actuated by means of the gearing connecting it to the fly-wheels D, substantialiy as andfor the purpose specified.

3. 1n a traction-engine, the combination of the crank rod R, beveled gearing k and n, wormshaft m, upright shaft o, with its pinions, and ljfth-wheel s, when arranged in the manner and for the purpose specified.

4. In a traction-engine, the frame-work consisting of the converging beams L, connected to the axles, as shown, and provided with a croSs-beannl), for upholding the spring-strips Y, connected at one end to the housing O, and at the other by the cross-spring Q, the whole arranged as and in the manner specified.

In testimony that 1 claim the foregoing as my own I atix my signature invpresence of two witnesses. Y
